That's why that worked. Hmm with short strings the null terminator could
be truncated when copying right? Something to look out for.
this is what I meant about truncation. S is no longer null terminated and
now the pchar will fail when passed to C libraries right?
var
s: String;
p: Pchar;
begin
s := 'hello';
p := @s;
S will still be null-terminated for ansistrings and shortstrings.
change to
s:=s+s;
p:=@s[1]; // and not @s
writeln(p[Length(s)+1]=#0);
this should have been p[Length(s)] obviously.
Michael.
